Truss-reinforced spacer grid and method of manufacturing the same

A truss-reinforced nuclear fuel rod spacer grid comprising:

• a truss structure in which horizontal trusses formed by horizontally weaving a plurality of truss members are vertically disposed at regular intervals, wherein:
• the horizontal trusses are shaped around a hexagon shaped space;
• the horizontal trusses are configured to deform outwardly and apply frictional force on a nuclear fuel rod upon insertion of the nuclear fuel rod;
• and
• an external plate joined with ends of the horizontal trusses and surrounding the truss structure and wherein the truss structure includes a cut guide tube hole configured for a guide tube wherein the guide tube is configured to accept a control rod.
